Application filed March 1, 1909. Serial No. 480,766.

Patented Feb. 15, 1910.

Be it known that I, JOSEPH F. MUBEIM, a citizen of the United States, residing at Warren, in the county of Worcester and State of Massachusetts, have invented new anduseful Improvements in Builder-Motions in Spinning-Frames, of which the following is a specification.

It is the object of th1s inventionto provide a construction whereby. a bunch ma be formed on the bobbin near its lower on as it stands in the spinning-frame before the builder-mechanism operates to build up the main body of the filling or yarn on the bobbin. It will be understood that the function of the bunch is to be bunch or cone or other similar appliance.

struck with a. feeler o erated by a feelermechanism which contro s the action of the filling-re lenishing mechanism, and, of course, t e device is only useful in a machine -where a. feeler-mechanism is employed. As the operation of a feeler on a on a bobbin is well known, .no description of itis deemed necessary.

The ordlnary method of winding thread on abobbin'for the purpose of producing a bunch is for the operator to lock the ringrail while it is at its lowest point, as is the case just before the bobbins are to be doiled,

' and then apply new bobbins to the s indles and start t e mechanism without un ocking the ring-rail, and run it until a sufiicient amount of filling is wound at the lower end of the bobbin to produce the bunch. As the ring-rail is locked thereis. necessarily N no traverse, and the bunches thus formed are soft, irre ular'and inadequately sha ed to receive the blows of the feeler. ivy means of my im roved mechanism the bunch is built soli ly and accurately and of the desired shape to receive the blows of the feeler for a suitablelength of time,

the ring-rail during the operation of bunchbuilding traversing or reciprocating vertically. When the bunch has been. built to the desired amount and extent, the ringrail automatically begins to traverse in the ordinary we point just a ove the bunch to the upper to wind the bobbin from a end'by means of well known builder-mechanism. By means of this invention thereforethe machine first builds the bunch and then proceeds to build the main portion of the filling above and next to the bunch.

The nature of the invention is fully de- .of the same, a portion of the frame being shown in horizontal section. Fig. 5 is a sectional detail illustrating the V bobbin when the bunch has been completed but be fore the builder-motion has wound upon the bobbin the main ortion of the filling. Fig. 6 is a View of tlie completely filled bobbin ready for dofling.

Similar numerals of reference indicate,

corresponding parts.

Reference-numeral 10 (Fig. 1) represents a portion of the frame of a spinningmachine, 11 is the spindle-rail, 12 the spindles, 13 the ring-rail, 14 the rings, 15 the lifter-rod, 16 the lifter-arm pivotally sup ported by a hanger 17 secured to the under side of the spindle-rail, and 18 the weight. or balance, all constructed as usual. Rigid on the shaft 19 (which is rigid with the lifter-arm 16) is an arm 20 to whose upper end is secured a cord or chain 21 which extends over the pulley 22 supported by the bracket or hanger 23 to the flanged wheel orpulley 24 which makes a part hi the builder-motion. This lmildvr-motion is not new, and the one illustrated is well known. but I will describe it briefly inasmuch as my improvement has some relation to it, the lmilder-motion being adapted to operate as soon as my bunclrhuildor mechanism (-ompletes its work. Briefly tlwrcforc, tho flanged wheel 24 (Figs. 1, 3 and 1-) is freely supported by a stud or short. shaft 25 extending horizontally from the swinging arm 26 pivotally supported at 2'? by the frame 10. The swinging arm is provided with ears 28 which constitutebearings for the shaft 29 whose conical end 30 is sustained by the right-hand bearing (Fig. 2). On the left end of the shaft is the hand doflingcrank 31, which is operated when thojbobbins are full and ready to be do'fl'od. The shaft 29 is provided with a worm 532 which engages with a gear-wheel 33 integral or rigid with the flanged wheel or pulley E24 and operates to turn it. The free end of the arm 26 supports a cam-roll 34 which is adapted to be brought into engagement by the weight 18, lifter-arm 16, arm 20, cord 21 and pulley 24, with the periphery of the cam-wheel 35 which is rigid on the driv ngshaft 36 supported by the frame and driven by suitable mechanism connecting withthe power. This, of course, vibrates the ringrail, subject to certain regulating parts be-.

A regulating or limiting-rod 44 extends from the arm up through the spindlerail,and is provided with the usual nuts 45 on opposite sides of the rail. By means of the upward and downward movements of the arm 39 the ratchet-wheel 42 is intermittently rotated by the engagement of the pawl 41 (against the power of the weighted arm 40) thus rendering the movement of the shaft 29 intermittent, said shaft by means of the worm 32 transmitting similar move ment to the gear-wheel 33 which is rigid with the flanged pulley 24, and this movement continues until the bobbins are full, when the arm is stopped by hand and the bobbins doifed in the ordinary manner. All the above-described builder-motion together v with its operation is well known, and needs no further description.

I will now describe my new and improved mechanism for forming the bunch on the bobbin before the builder-motion applies the main portion 37 of the filling, said bunch being representedat 46 in Figs.- 5 and 6. l'vfounted on the same driving shaft 36 which imparts rotation to the cam-wheel 35 (Figs. 2, and 4') is'a cam-wheel 47, its periphery 3 i sing arranged with short cam portions of length to produce and build by means of connecting mechanism the layers in-the short bunch 46. This cam-wheel has a slightly beveled eriphery, the bevel being inward toward t e-right end of the machine, that is,'toward the inner end of the shaft 36. Also mounted on this shaft near its unsupported end (the outer end of the shaft having bearings me long box 48) is the sprocketwheel '49 which is connected by a chain 50 (Figs. 2 and 4) with a sprocket-wheel 51 supported by a horizo tal. shaft 52 having its bearings in boxes 5; and 54 supported by a bracket 55 secured at 56 to the swinging arm 26. On this shaft 52 near its outer end is mounted a sprocket-wheel 57 which is connected by a chain 58 with a sprocket-3 wheel 59 whose hub 60 rests'on and is sup-f ported by a yoke 61 which is integral with a horizontal bar 62, said bar 62 extending? from and being rigidly secured at 63 to the swinging arm 26. This bar has upward extensions 64 and 65 in which is mounted a horizontal shaft 66 which is provided with a sleeve 67 formed with a worm 68 which extends into a corresponding spiral root-e or thread 69 on the inner surface 0 the hub 60 of said sprocket-wheel 59. On the outer end of this horizontal shaft 66 is a-handwheel 70 and between its bearing points a 7 ratchet-wheel 71 is rigid on the shaft, said ratchet-wheel being engaged by the upper end of a dog or pawl 72 which is pivotally supported at 73 by the arm 26 and lies in said wheel by gravity. By this means the 0 shaft is held normally stationary. The in ner end of the shaft is provided with a cam- -roll 74, and by means of the worm 68 and the hand-wheel 70 this cam-roll may be moved horizontally into engagement with $5 the peripherv of the cam-wheel 47.

Each depression in the cam 47 represents one traverse or vibration over that part of the bobbin which receives the bunch, and, as

is evident, the traverse represents the length go of the. bunch. When the cam-roll 74 has been brought into engagement with the camwheel 47 by rotating the handle 70 and moving the shaft 66 longitudinally in the threaded sprocket-wheel 59, 60, the traverse is ro- 915 duced solely by means of the cam-whee 47,

as the cam-wheel 35 and cam-roll 34 are out .of engagement. As long as the cam-roll 741 I remains in engagement the machine is confined to working on the bunch, and it remains in engagement with the cam 47 until the worm 69 has gradually drawn the shaft 66 (which is prevented from rotation by the dog 72) out far enough to disengage the cam-roll 74 from the cam 47. draw'al of the shaft is of course produced by the rotation of the internally threaded sprocket-wheel 59, 60, which is driven by the chain 58, sprocket 57, shaft 52, sprocket 51,

chain 50, and sprocket 49, on the drivingshaft 36. When the cam-roll 74 has reached the point of disengagement, the bunch is built, and the regular builder-motion begins by reason of the cam-roll 34 beingswung up.

into engagement with the cam-wheel 35 by the swinging arm 26. It will readily be seen that by means of the relative positions as to height of the cam-roll 74 and the camroll 34, the latter cam-roll 34 cannot reach the cam 35 until the oam-roll 74, which has I been held up in engagement with "the cam" 47 is withdrawn from the periphery of said cam and swung up beyond its periphery by the bar 26. Of course this swinging bar 1s constantly being pressed upward by the action of the weight 18 through the mechanism 16, 20, 21, 24, and the bar 62 with the shaft 66 and cam-roll 74 must all be swung up at the same time. If therefore, the camroll 74 is in line with the cam it must as This with 105 horizontally fromsuch engagement by the action of the threaded wheel 59, 60, and

' worm 68, there is nothing to prevent the bunch-building mechanismis again 7 what Iiclaim, and

l thereon one of whic the other end with-a hand actuating device, a a sleeve'rigid on said shaft and cam-roll 34 which is also supported by the swinging arm 26 from being lifted into engagement with the cam 35. Hence the cam 35 immediately throu h the building mechanism begins to win the filling and pro duce the main portion 37 in the ordinary manner, the short traverse produced by the cam 47 givin' place to the lon traverse produced by t e cam 35. After oflin thg ace in operation by swinging down the 0g or pawl and turning the wheel 70 by'hand.

By means of the beveled edge or periphery of the cam 47 the roll 74 is, when the shaft 66 is withdrawn by means of the worm 68, 69, moved up gradually, thus producing the taper on the bunch. 4
